* How do the [[spoiler:Gyroids]] cause people to [[spoiler:turn into fucked-up animals]]? And how can it be [[spoiler:just the one you like the most]]? Aren't they just normal random pieces of normal random furniture?
** Oh, wait, each of them causes you to [[spoiler:turn into a different animal]]. The villagers [[spoiler:bury specific Gyroids]] depending on your [[spoiler:favourite animal]]. For example, [[spoiler:Quazoids cause you to turn into a rabbit]]. Which explains why Billy can't find other kinds, also why he [[spoiler:is surrounded by them in the anti-box ending]]. That still leaves one question: HOW can a [[spoiler:simple statue-ish thing turn you into an animal]]?
*** [[AWizardDIdIt Magic]]. Evil, eldritch magic.
*** [[spoiler:It's a story about a fucked up prison island where the locals trap kids for their body parts. And they're actually ''nicer'' now that Tom Nook runs the store.]] Just go with it.
*** It's really a case of NothingIsScarier. Billy mentions a few theories in-universe, but the truth is that he doesn't know and neither should the audience. But it's probably magic.
